Merge branch 'nfs-for-2.6.34' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6
* 'nfs-for-2.6.34' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6: (44 commits) NFS: Remove requirement for inode->i_mutex from nfs_invalidate_mapping NFS: Clean up nfs_sync_mapping NFS: Simplify nfs_wb_page() NFS: Replace __nfs_write_mapping with sync_inode() NFS: Simplify nfs_wb_page_cancel() NFS: Ensure inode is always marked I_DIRTY_DATASYNC, if it has unstable pages NFS: Run COMMIT as an asynchronous RPC call when wbc->for_background is set NFS: Reduce the number of unnecessary COMMIT calls NFS: Add a count of the number of unstable writes carried by an inode NFS: Cleanup - move nfs_write_inode() into fs/nfs/write.c nfs41 fix NFS4ERR_CLID_INUSE for exchange id NFS: Fix an allocation-under-spinlock bug SUNRPC: Handle EINVAL error returns from the TCP connect operation NFSv4.1: Various fixes to the sequence flag error handling nfs4: renewd renew operations should take/put a client reference nfs41: renewd sequence operations should take/put client reference nfs: prevent backlogging of renewd requests nfs: kill renewd before clearing client minor version NFS: Make close(2) asynchronous when closing NFS O_DIRECT files NFS: Improve NFS iostat byte count accuracy for writes ...
